The first summer living with my two new half-sisters after my father's remarriage! Two incredibly cute and busty sisters! As an older brother, I shouldn't be conscious of them, yet I can't help but stare at their chests! Plus, it's a tropical night and the air conditioner is broken, making it unbearably hot! My sisters, unable to bear it, wear light clothing, and their sweat-soaked busty nipples have me glued to the spot!! Then, they suggest sleeping in my room, the only one in the house with a working air conditioner. Trapped between their see-through busty bodies, and with such close contact, my arousal level exceeds 120%! There's no way I can hold back...
